Replacing my effluent pump

[lwparchive]

Is the only difference between a goulds epo411a and a epo411ac pump the length of the power cable? does total dynamic head mean vertical lift?What does a float switch style piggyback/wide angle mean? I need to replace my effluent pump.

The difference between the two pumps is the length of the cords. Piggy Back wide angle floats mean the pump plug into the float switch and the float switch plugs into the receptacle. Wide angle means there is a up and down radius the float follows based on the depth of the water. TDH means vertical push.
